    Answer:

    q = 5 startroot 5 endroot

    q = Negative 5 startroot 5 endroot

    Step-by-step explanation:

    q² – 125 = 0

    q² = 125

    q = +/- sqrt(125)

    q = +/- 5sqrt(5)

    Answer:

    5\sqrt{5} and -5\sqrt{5}

    Step-by-step explanation:

    We want to find roots of the function: f(q)=q^2-125. The roots are the numbers that make the function f(q) = 0. So set the expression equal to 0:

    q^2-125=0

    Add 125 to both sides:

    q^2=125

    Square root both sides:

    q= +/- \sqrt{125} = +/- \sqrt{5^2*5} = +/- 5\sqrt{5}

    So, the answers are 5\sqrt{5} and -5\sqrt{5}. (Sorry, I can’t tell what the answer choices are)

    Hope this helps!
